摘要:目的  對新辅助内分泌治疗和新辅助化疗在乳腺癌治疗中的短期疗效进行系统评价,以期为临床诊疗工作中新辅助治疗方式的选择提供参考。方法  通过检索中国知网、万方、维普、中国期刊网全文数据库和Cochrane Library、PubMed、EMBASE、Web of Science等数据库,检索出直接比较新辅助内分泌治疗和新辅助化疗短期疗效的文献,采用RevMan 5.3作为数据分析工具进行Meta分析,比较两种方法的肿瘤缓解率(RR)、临床完全缓解率(cCR)、病理完全缓解率(pCR)和保乳率(BCS)。结果  最后纳入13篇文献,共1380例乳腺癌患者,其中新辅助内分泌组为598例(43.33%),新辅助化疗组为782例(56.67%)。Meta分析结果显示:在ER阳性患者中,两组RR[OR=0.79,95%CI(0.58,1.06),P=0.12]、cCR[OR=0.45,95%CI(0.15,1.39),P=0.16]、pCR[OR=0.56,95%CI(0.28,1.13),P=0.10]、BCS[OR=1.23,95%CI(0.83,1.82),P=0.29]比较,差异无统计学意义(P>0.05);在HER-2阴性患者中,两组cCR[OR=0.38,95%CI(0.06,2.33),P=0.30]、pCR[OR=0.56,95%CI(0.24,1.32),P=0.19]比较,差异无统计学意义(P>0.05)。结论  ER阳性、HER-2阴性的乳腺癌患者行新辅助内分泌治疗可以获得与新辅助化疗相似的疗效,但尚未表现出优势。新辅助内分泌治疗并不能使ER阳性患者得到更多获益。

Abstract:Objective  To systematically evaluate the short-term efficacy of neoadjuvant endocrine therapy and neoadjuvant chemotherapy in breast cancer treatment, with a view to providing a reference for the selection of neoadjuvant treatment methods in clinical diagnosis and treatment.Methods  By searching China HowNet, Wanfang, Weipu, China Journal Net full-text database and Cochrane Library, PubMed, EMBASE, Web of Science and other databases, we retrieved the literature that directly compared the short-term efficacy of neoadjuvant endocrine therapy and neoadjuvant chemotherapy, using RevMan 5.3 Meta analysis as a data analysis tool, comparing the tumor remission rate (RR), clinical complete remission rate (cCR), pathological complete remission rate (pCR) and breast-conservation rate (BCS) of the two methods. Results  Finally, 13 articles were included, a total of 1380 breast cancer patients, including 598 cases (43.33%) in the neoadjuvant endocrine group and 782 cases (56.67%) in the neoadjuvant chemotherapy group. Meta analysis results showed that: in ER-positive patients, RR [OR=0.79, 95%CI(0.58, 1.06),P=0.12], cCR (OR=0.45,95%CI(0.15,1.39),P=0.16), pCR[OR=0.56, 95%CI(0.28, 1.13), P=0.10], BCS [OR=1.23, 95%CI(0.83, 1.82), P=0.29], the difference was not statistically significant(P>0.05); In HER-2 negative patients, cCR[OR=0.38, 95%CI(0.06, 2.33), P=0.30], pCR [OR=0.56, 95%CI(0.24, 1.32), P=0.19],the difference was not statistically significant (P>0.05).Conclusion  Neoadjuvant endocrine therapy for breast cancer patients with ER positive and HER-2 negative can obtain similar efficacy as neoadjuvant chemotherapy, but has not shown advantages. Neoadjuvant endocrine therapy does not benefit patients with positive ER.

乳腺癌(breast cancer)是一种常见的恶性肿瘤,发病率位居女性恶性肿瘤的首位[1]。近年来,乳腺癌的发病率与死亡率呈现逐年上升的趋势,并且在女性全部恶性肿瘤的发病、死亡中的占比也有所增  加[2,3]。乳腺癌的治疗有多种方式,研究显示[4],在行手术治疗之前进行新辅助治疗能有效地增强临床疗效,新辅助治疗已成为治疗早期乳腺癌的重要手段之一。常见的新辅助治疗方式包括新辅助化疗(NCT)、新辅助内分泌治疗(NHT/NET)、新辅助抗人类表皮生长因子受体2(HER-2)治疗。一直以来……
